Description

Technical Field

[0001] This utility model relates to a drawer-type vehicle refrigerator, and more particularly to a semi-drive drawer-type vehicle refrigerator. Background Technology

[0002] Drawer-type car refrigerators usually require users to manually push the drawer fully in to ensure a tight seal. However, manually pushing the drawer fully in can result in inconsistent closing force, which can easily lead to poor sealing.

[0003] Patent CN118602679A discloses a car refrigerator with a self-closing function, comprising: a fixed base; a drawer slidably mounted on the fixed base; a self-closing unit mounted on the fixed base and having a track groove and a sliding block, the track groove having a straight section and a bent section, one end of the sliding block being movably inserted into the track groove, and the other end being movably engaged with the drawer; when the drawer is in the self-closing position, the self-closing unit drives the sliding block to slide along the straight section of the track groove, thereby driving the drawer engaged with the sliding block to slide along the fixed base to the closed position; a first drive unit mounted on the fixed base for disengaging the drawer from the sliding block; and a second drive unit mounted on the fixed base for moving the drawer to the maximum unfolded position.

[0004] The above technology has solved the problem of poor sealing when closing doors to a certain extent. However, when the drawer returns from its fully extended position to the self-closing position, the self-closing unit needs to be driven to make the sliding block engage with the drawer again. This requires a high degree of precision in the position of the sliding block, which undoubtedly increases the overall structural technical difficulty. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a semi-drive drawer-type vehicle refrigerator.

[0006] The technical solution adopted by this utility model to solve the problem is: a semi-driven drawer-type vehicle refrigerator, including a fixed base and a drawer that slides back and forth on the fixed base. The drawer has a maximum unfolded position, a self-driven position, and a fully closed position during its travel on the fixed base. A drive unit is installed on the fixed base, and the drive unit drives the drawer to slide from the self-driven position to the fully closed position. The drive unit includes a track and a sliding block slidably connected to the track. The track is arranged in a front-back direction. The track includes a straight section, and the front end of the straight section is bent downward to form a bent section. A locking part is provided at the bottom of the drawer, and a front stop and a rear stop are provided at the top of the sliding block. There is a locking position between the front stop and the rear stop. When the drawer is pushed from the maximum unfolded position to the self-driven position, the locking part abuts against and pushes the rear stop, the sliding block slides from the bent section into the straight section, the front stop approaches the locking part and abuts against the front end of the locking part, and the locking part is locked in the locking position.

[0007] As a further improvement to the above technical solution, a limit block is also provided at the bottom of the drawer, and a stop buffer is fixedly connected to the fixed base. When the drawer slides to the maximum unfolded position, the limit block abuts against the stop buffer.

[0008] As a further improvement to the above technical solution, there are two limiting blocks, which are respectively arranged on the left and right sides of the snap-fit ​​part, and the number and position of the stop buffers correspond to the limiting blocks.

[0009] As a further improvement to the above technical solution, a damping roller is also installed on the fixing base, and the damping roller abuts against the bottom of the drawer.

[0010] As a further improvement to the above technical solution, the drive unit includes a mounting groove, the rails are arranged on the left and right side walls of the mounting groove, the two rails are symmetrical to each other, and the sliding block is provided with connecting posts on both the left and right sides, the connecting posts being inserted into the rails.

[0011] As a further improvement to the above technical solution, a lead screw is installed in the mounting groove, the lead screw is arranged in the front-to-back direction, and the lead screw is electrically connected to a drive motor; a transmission component is screwed onto the lead screw, and a sliding block is hinged to the transmission component; the drive motor drives the lead screw to rotate, and the rotation of the lead screw causes the transmission component and the sliding block to move back and forth.

[0012] As a further improvement to the above technical solution, a position sensor is also included, which is communicatively connected to the drive motor and is used to identify the position of the drawer.

[0013] As a further improvement to the above technical solution, a Hall sensor is also included, which is communicatively connected to the drive motor and is used to identify the rotation status of the drive motor.

[0014] As a further improvement to the above technical solution, a control button is also included, which is electrically connected to the drive motor.

[0015] As a further improvement to the above technical solution, the bottom of the sliding block is provided with a clearance groove, and when the sliding block slides into the bent section, the lead screw enters the clearance groove.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a downwardly curved section at the front end of the straight section, and a front stop and a rear stop are provided at the top of the sliding block. When the drawer returns from the maximum unfolded position to the self-drive position, the sliding block slides out of the curved section, and the front stop approaches the locking part and abuts against the front end of the locking part, thereby restoring the locking part and the sliding block. The structure is simple and feasible. Attached Figure Description

[0036] Reference Figures 1 to 13 A semi-driven drawer-type vehicle refrigerator includes a fixed base 1 and a drawer 2 that slides back and forth on the fixed base 1. The drawer 2 has a maximum extended position, a self-driven position, and a fully closed position during its travel on the fixed base 1. A drive unit is mounted on the fixed base 1, which drives the drawer 2 to slide from the self-driven position to the fully closed position. The drive unit includes a track 111 and a sliding block 114 slidably connected to the track 111. The track 111 is arranged in a back-to-back direction. The track 111 includes a straight section 1111, the front end of which is bent downwards to form a bent section 1112. The bottom of the drawer 2 is provided with... The locking part 21 has a front stop 1143 and a rear stop 1144 on the top of the sliding block 114, and a locking position 1145 between the front stop 1143 and the rear stop 1144. When the drawer 2 is pushed from the fully extended position to the self-driven position, the locking part 21 abuts against and pushes the rear stop 1144, the sliding block 114 slides from the bent section 1112 into the straight section 1111, the front stop 1143 approaches the locking part 21 and abuts against the front end of the locking part 21, and the locking part 21 is locked in the locking position 1145, thereby restoring the locking connection between the locking part 21 and the sliding block 114. The structure is simple and feasible.

[0037] Specifically, the drawer 2's travel on the fixed base 1 also includes an unlocked position (the drawer 2 passes through a self-driven position and an unlocked position sequentially from the fully closed position to the maximum unfolded position). The drive unit drives the drawer 2 to slide from the fully closed position to the unlocked position. When the drive unit drives the drawer 2 to slide from the fully closed position to the unlocked position, the sliding block 114 slides from the straight section 1111 into the bent section 1112, and the front stop 1143 rotates down and moves away from the latching part 21, thereby canceling the restriction on the latching part 21 from the front end. When the drawer 2 is in the unlocked position, the user can manually pull the drawer 2 to the maximum unfolded position.

[0038] In a preferred embodiment, the distance between the fully closed position and the unlocked position is preferably 60 mm.

[0039] In a preferred embodiment, a limit block 22 is also provided at the bottom of the drawer 2, and a stop buffer 13 is fixedly connected to the fixed base 1. When the drawer 2 slides to the maximum unfolded position, the limit block 22 abuts against the stop buffer 13. The stop buffer 13 is used to limit the maximum unfolded position of the drawer 2 and reduce the wear of internal components.

[0040] In a preferred embodiment, there are two limiting blocks 22, which are respectively disposed on the left and right sides of the latching part 21. The number and position of the stop buffers 13 correspond to the limiting blocks 22, thereby preventing the drawer 2 from shifting position.

[0041] In a preferred embodiment, a damping roller 14 is also installed on the fixed base 1. The damping roller 14 abuts against the bottom of the drawer 2, providing a comfortable pull-out feel in the manual drive section (between the unlocked position and the maximum unfolded position).

[0042] In some embodiments, the drive unit includes a mounting groove 11, and the rails 111 are disposed on the left and right side walls of the mounting groove 11. The two rails 111 are symmetrical to each other. The left and right sides of the sliding block 114 are provided with connecting posts 1141, and the connecting posts 1141 are inserted into the rails 111.

[0043] In some embodiments, a lead screw 112 is installed in the mounting groove 11. The lead screw 112 is arranged in the front-to-back direction. The lead screw 112 is electrically connected to a drive motor 12, and the drive motor 12 drives the lead screw 112 to rotate. A transmission member 113 is screwed onto the lead screw 112, and the rear end of the sliding block 114 is hinged to the transmission member 113. The drive motor 12 drives the lead screw 112 to rotate, and the rotation of the lead screw 112 causes the transmission member 113 and the sliding block 114 to move back and forth.

[0044] In other possible embodiments, the above-described screw drive scheme can also be replaced by gear rack, pulley, wire rope, or other transmission methods.

[0045] In a preferred embodiment, a position sensor is also included. The position sensor is communicatively connected to the drive motor 12. The position sensor is used to identify the position of the drawer 2. When the sliding block 114 is engaged in the locking position 1145 and the drawer 2 is in the self-driven position, the drive motor 12 is activated and rotates, causing the drawer 2 to slide from the self-driven position to the fully closed position.

[0046] In other possible embodiments, the position sensor described above can be replaced with a Hall sensor, which is communicatively connected to the drive motor 12. The Hall sensor is used to identify the rotation of the drive motor 12. When the drawer 2 pushes the sliding block 114, the sliding block 114 drives the drive motor 12 to rotate in the opposite direction. The Hall sensor identifies the rotation of the drive motor 12 and starts the drive motor 12. The drive motor 12 rotates, causing the drawer 2 to slide from the self-driven position to the fully closed position.

[0047] Specifically, in some embodiments, the vehicle refrigerator is also provided with a control button, which is electrically connected to the drive motor 12. Pressing the control button causes the drawer 2 to slide forward to the unlocked position.

[0048] Specifically, in some embodiments, the bottom of the sliding block 114 is provided with a clearance groove 1142. When the sliding block 114 slides into the bent section 1112, the front end of the sliding block 114 rotates downward and the lead screw 112 enters the clearance groove 1142.

[0049] refer to Figure 4 , Figure 8 as well as Figure 10 Opening principle: Pressing the control button drives the drive motor 12 to drive the lead screw to rotate in the forward direction. The transmission component 113 drives the sliding block 114 and the drawer 2 to slide forward. When the drawer 2 slides to the unlocked position, the front stop 1143 moves downward due to the sliding block 114 entering the bending section 1112, thereby canceling the limit at the front end of the locking part 21. Then, the drawer 2 can be manually pulled out from the unlocked position to the maximum unfolded position.

[0050] refer to Figure 10 , Figure 6 as well as Figure 4 Closing principle: When the drawer 2 is manually pushed, it slides backward. The rear side of the locking part 21 abuts against the rear stop 1144 and pushes the rear stop 1144. The rear part drives the sliding block 114 to rotate and disengage from the bent section 1112. At this time, the front stop 1143 moves up and abuts against the front end of the locking part 21. The locking part 21 is engaged in the locking position 1145 and reaches the self-driven position. After the position sensor or Hall sensor recognizes it, it feeds back to the drive motor 12. The drive motor 12 rotates in the opposite direction, sliding the drawer 2 from the self-driven position to the fully closed position, thereby achieving a semi-driven effect.

[0051] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
